h4de5 Posted January 19, 2006 Share Posted January 19, 2006 hi, today i got my new memory: 2x CMS512-3200C2Pro. i ordered them yesterday so i was quiet happy to hold them in my hands already. so i unplugged my pc, get my old memory (2x256mb pc2600) out, installed the new ones, plugged it in and hit the power button. i was kinda disappointed when i here the four magic words: "system failed memory test" i've got 4 memory slots and so i tried out a few varitions with the new and the old dimms. but nothing worked well. after reading the documentations again i was worried if those dimms really fit. it says it supports PC1600 und pc2100 dimms, nothing about pc3200. next i put in my old dimms and started searching the web for help. i found some helpful articels and posts. most of them told me, that pc3200 and the p4g8x just work fine together - but most of the users have a fsb of 200mhz und i can just get 133-150mhz, cause my p4 2.53ghz won't work at those frequencies. after that i gave them a last try: i put every single dimm in every slot and suddenly it worked. a single 512mb dimm in slot1. bios ok, windows ok, and i'll run memtest later. the system won't boot if i put the other dimm in any slot. so my questions: is it even possible to run those dimms in dualchannel on a p4g8x and 133mhz fsb? i can't boot with the second dimm installed - so i can't run memory tests for it. is it even possible to exchange the dimm under guarantee? specs: Asus P4G8x Deluxe (Intel 7205 granite bay) Pentium 4 2.53 Ghz (19x 133Mhz) Radeon 9500 Pro TwinX1024-3200c2pro Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted January 19, 2006 Corsair Employees Share Posted January 19, 2006 Please make sure that you have the latest bios and then load setup defaults and see if it will post. But this MB will only support DDR266 and may not post with DDR400 memory. Link to comment Share on other sites More sharing options...
h4de5 Posted January 19, 2006 Author Share Posted January 19, 2006 wow you are fast :eek: thanks. yes i've the latest bios on it (1007.002) yes its a beta bios, i needed it for my tv-card. i've loaded the bios defaults first of all. so no overclocking, no overvolting und no user defined timings or someting. currently i'm running a single DDR400 dimm. aida says: 2-2-2-6 timings (by spd) can i give you any more information?

Corsair Employees RAM GUY Posted January 19, 2006 Corsair Employees Share Posted January 19, 2006 Try setting the timings manually to Cas 2-3-3-6 and I would set the memory voltage to 2.7 Volts as well. Link to comment Share on other sites More sharing options...
h4de5 Posted January 19, 2006 Author Share Posted January 19, 2006 i'll give it a try. will be here right again. i read some posts in here, but i don't know why you recommend 2.7 volts? what is the advantage of it? (don't wanna criticize you - i just don't know) Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted January 19, 2006 Corsair Employees Share Posted January 19, 2006 Adding more voltage will help to improve memory performance and stability. In additon, DDR400 spec for memory voltage is 2.6 Volts +- .1 volt and JEDEC spec for PC-2100 was 2.5 Volts +- .1 Volt since the MB is likely set for PC-2100 it may be under volting the memory.

h4de5 Posted January 19, 2006 Author Share Posted January 19, 2006 ok. i set it to 2.7 volt and the timings to 2-3-3-6. still the same problem. the first dimm is (currently) running. when i put in the second one, it says "system failed memory test". regardless if i plug it in together or alone in any other slot.

h4de5 Posted January 20, 2006 Author Share Posted January 20, 2006 thank you for your help so far. i bougth this memory by an reseller in austria and told him today about this case. i think i should wait what they say bout it and if they will replace it, i'd prefer this, because it could be faster on that way. ps: as i read in other posts here, some users were very irritated when they tried to change their timings on an p4g8x and nothing happend. maybe you know it already - its a bios bug which was fixed afaik in version 1006 (or in the tweaked 1005 version from http://www.x86-secrets.com) Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted January 21, 2006 Corsair Employees Share Posted January 21, 2006 If they have a mention of this problem and have a bios that may solve it I would give it a try. Link to comment Share on other sites More sharing options...
